After all I fiddled around a bit and tried out some programswhich worked fine until I got the upper message print out onconsole. I immediately rebooted the system with no problems.Afterwards I removed a printjob (initiated from WIN95 viaSAMBA, driving lprng). This job took about 45 megabyte memory(during all that printing of this special job was reinitiatedand progressed). The person who invoked the printjob told meabout some problems that he had with the server in acceptinghis job (/tmp is a link to /var/tmp, /dev/hda6 is mounted on/var and of 245861 kB size with about 213613 kB free if thereare no printjobs).

Since I've removed this 45 MB job (about six hours ago),no problems occured and the system is stable so far.

Possible reasons might be - although I'm not certain:

1) I recompiled the kernel (kernel-source-2.0.30-1) myselfand unset some of the hardware flags in make config (workaroundsfor some buggy chipsets). I did this because I'm using aGigabyte 586 board with Intels HX chipset.

2) The harddisk got corrupted? I consider this, because of theabove described happenings.
